Boroux is the water filter that stepped into the Berkey gap: a US-made gravity system whose Foundation filter elements are engineered as direct drop-in replacements for Black Berkey elements, so it fits the housings a huge number of households already own.
The Legacy is a countertop gravity system: fill the top chamber, and water drips through the filter elements into the lower reservoir with no plumbing, no electricity, and no water pressure required. That makes it the standard pick for renters, off-grid setups, emergency preparedness, and anyone who does not want to install an under-sink system.
Boroux is a family company in Pueblo, Colorado, and its filtration is WQA-certified to NSF standards, which is the third-party testing benchmark to look for in this category. The strategic hook is the Foundation element being a Black Berkey-compatible replacement, which matters because Berkey itself has faced supply and regulatory turbulence, leaving a lot of orphaned housings.
The Legacy system runs about $355 to $455, with stainless and stand bundles up to $510, and Boroux runs frequent sale pricing. The main ongoing cost is replacement elements, sold separately.
Renters and preparedness-minded buyers who want a no-plumbing countertop gravity filter with third-party certification, and current Berkey owners who need compatible replacement elements.
You want the highest flow rate and set-and-forget convenience of a plumbed under-sink or whole-house system, or you do not have counter space for a two-chamber unit.

Does the Boroux Legacy need plumbing or electricity?
No. It is a gravity system: you pour water into the upper chamber and it filters down into the lower reservoir with no plumbing, no power, and no water pressure. That is what makes it suited to renters, off-grid use, and emergency preparedness.
